There is a wide variety of data quality attributes such as the ones proposed by the ISO/IEC organization and also by many other domestic and international institutions. However, it takes considerable time and costs to apply those criteria and guidelines to real environment. Therefore, it needs to define data quality evaluation attributes which are easily applicable and are not influenced by organizational environment limitations. The purpose of this paper is to derive data quality attributes and order of their priorities based on customer requirements for managing the process systematically and evaluating the data quantitatively. This study identifies the customer cognitive constructs of data quality attributes using the RGT(Repertory Grid Technique) based on a Korean quality standard model (DQC-M). Also the correlation analysis on the identified constructs is conducted, and the evaluation attributes is prioritized and ranked using the AHP. As the results of this paper, the consistent system, the accurate data, the efficient environment, the flexible management, and the continuous improvement are derived at the first level of the data quality evaluation attributes. Also, Control Compliance(13%), Regulatory Compliance(10%), Requirement Completeness(9.6%), Accuracy(8.4%), and Traceability(6.8%) are ranked on the top 5 of the 19 attributes in the second level.

The purpose of this study is to find out whether changed interactions due to reformatting has a significant effect on the play attribute of children's play from an instrumental point of view. Based on the study of Roser Caillois theory of play (Agon, Mimicry, Area, Ilinx) and previous studies, a questionnaire was written and experimental design was carried out through brick stack which are most preferred in the whole development of children. Brick stack were selected from physical and electronic spaces and the survey was conducted with children's experiences by dividing into experimental group and comparative group. Correlation and T-test results, the brick stack by reformating showed significant difference in the play attributes (Agon, Mimicry, Area, Ilinx) of Rose Caillois and we found that the effectiveness of play is doubled in the electronic space. Play properties evenly distributed in electronic space brick stacking suggest that pleasure and fun can double.

Icon is a small graphic which represents a particular function in computer interface. Comprehension and learning of icons are needed for using them because they represent some meanings. This study was conducted to examine which were more important factors in using icons. First, representational characteristics of icons were examined. Second, using a eyetracker, the way of coding of redundant display was examined which removed obscurity of display and gave more meaning to a user. Icons using attribute of object and direct discription of action were more efficient than icons of other representational form in comprehension. Redundant display was proved to have some advantages, especially when the icons had low familarity. Visual information processing of icons were discussed according to familarity and learning.

소프트웨어 아키텍처는 소프트웨어 컴퍼넌트와 이들 컴퍼넌트들 간의 상호 관계를 나타내는 시스템의 전체적인 구조이다. 이때 완성된 시스템이 품질에 대한 요구를 만족시키는 시스템인지의 여부를 결정하는 아키텍처의 평가가 매우 중요하다. 그러나 평가 과정에서 아키텍처에 대한 부적절하거나 모호한 표현으로 인해 광범위한 응용에서는 않은 제약이 따른다. 그러므로 본 논문에서는 소프트웨어 아키텍처를 평가하기 위해 준비하고, 실행하고, 완료하는 세 가지 단계 제시한다. 이들 단계를 수행함에 따라 품질 속성의 획득에 많은 영향을 주는 아키텍처의 설계 결정을 중심으로 체계적인 아키텍처 평가가 이루어질 수 있다.

지능 로봇은 표현 가능한 사물, 공간을 모델링하기 위해 주변 환경을 인지하고, 자신이 수행할 수 있는 행동을 결합하여 임무를 수행하게 된다. 이를 위해 온톨로지를 사용하여 사물, 공간, 상황 및 행동을 표현하고 특정 임무 수행을 위한 자바 기반 Rule을 통해 다양한 추론 방법을 제공하는 로봇 지식 체계를 사용하였다. 사용된 로봇 지식 체계는 생성되는 인스턴스가 자료의 클래스와 속성 값이 일관성 있고 다른 자료와 모순되지 않음을 보장해 준다. 이러한 로봇 지식 체계를 효율적으로 사용하기 위해서는 완전한 온톨로지 인스턴스의 생성이 밑받침 되어야 한다. 하지만 실제 환경에서 로봇이 Vision Sensor를 통해 사물을 인식할 때 False Positive False Negative와 같은 인식 오류를 발생시키는 문제점이 있다. 이를 보완 하기 위해 본 논문에서는 물체와 물체간의 Spatial Relation, Temporal Relation과 각 물체마다의 인식률 및 속성을 고려하여 물체 인식 오류에서도 안정적으로 인스턴스 관리를 가능하게 하는 Rule 기반의 일식오류 검출 필터를 제안한다.

This paper explores the elements of FRBR entities to create entities records from MARC records automatically. Attributes of entities analyzed and embodied in MARC records. FRBR records are cited as examples separately. And problems of applying FRBR model are suggested. The result of this paper is expected to keep up with the shift of cataloging's environment and influence system design.

This study aims to give a syntactic and semantic analysis of the phe- nomenon of Quantifier Floating in the framework of Generalixed Cate- gorial Grammar. Floated quantifiers like neys-i as in Hakayngtul-i neys-i swul-ul masyessta are syntactically analyxed as VP modifiers(VP/VP), and semantically as involving nominalixed properties. Related forms like neys(NP/NP) and neys-ul(TV-TV) are also given rigorous syntactic and semantic analysis. A successful anaysis sheds light on the possiblity of using Categorial Grammar, which is subject to adjacency principle, for the (computer) processing od Korean.

기존의 감성 연구들은 주회 배색이나 형태등과 관련된 정적인 장면 위주로 수행되었다. 기술의 발달로 역동적인 디스플레이가 가능해지면서 동적인 장면을 대상으로 한 감성연구의 필요성이 요구된다. 본 연구에서는 움직임과 관련된 감성어휘를 추출하여 감성 차원을 밝히고 움직임과 관련된 속성을 살펴보았다. 다양한 방법을 통해 수집된 감성어휘를 적절성 평가를 통해 70개로 정리한 뒤 요인분석을 통해 각 요인을 대표하는 19개의 기본 감성 어휘를 추출하였다. 움직임 패턴을 제시하면서 19개의 감성어휘를 기초로 움직임에서 의 감성을 평정하도록 하였다. 다차원 척도법을 이용하여 분석한 결과 움직임에 대한 감성 차원은 '적극적이다-소극적이다'의 차원과 ‘밝다-어둡다’의 두 차원으로 대부분 설명 될 수 있음을 확인하였다. 움직이는 속도와 진행 경로를 변화시키면서 두 가지 감성 차원에 따라 움직임에서의 감성을 평가하도록 하였다. 움직이는 속도와 곡선 경로의 진폭이 움직임에서의 감성 차원을 결정하는 중요한 요소로 작용하는 경향을 보였다.

In the Pohang-Gampo area, several diatomite beds occurred in mostly thinner than 1 m are embedded in the Pohang Formation of marine environment and the pyroclastic Eoil Formation. The diatomite from the Eoil Formation is constituting the high-grade ore altered slightly by diagenesis. In contrast, the diatomite intercalated within the upper horizon of the Yeonil Group is comparatively low-grade and highly altered in places. During diagenesis, an increasing of crystallinity of opal, i.e., the original mineral component of diatom, results in ultimately the mineral transition to quartz with accompanying a drastic change in morphology and texture of the altered diatomite. The diagenetic alteration appears to have undergone by way of the chemical diagenesis, which is largely controlled by degree of fluid contact, rather than burial diagenesis. For the diatomite from the Pohang-Gampo area, careful SEM observations, XRD, chemical analyses, and determination of specific surface area were done to identify the fossil species, mineral and chemical composition, and other physical properties in the view of assesment of grade and quality. The domestic diatomite ores are evaluated to be not good in grade and quality, compared to those of famous foreign localities. However, some diatomite deposits of marin,: origin from the Pohang Formation is constituting a peculiar clay-rich type, i.e., moler applicable to the special usage such as a manufacturing of lightweight brick. Because such a diatomite is frequently intercalated relatively as a thicker bed in the upper part of the Yeonil Group, a systematic and careful investigation should be done for the exploitation and development of an economic diatomite deposit of the moler type.

This study empirically analyzes the relationships among the road and traffic experts' personal characteristics, the driving behavior and factors being expected to have an effect on the satisfaction about roundabout operation. The factors are drawn and grouped through the principle component analysis to clarify driving environment satisfaction on roundabout operation. Each group is named as personal attribute, driving behavior attribute, and satisfaction. After the variables are refined by confirmatory factor analysis, satisfaction model is developed with personal attribute and driving behavior attributes as exogenous variables and roundabout driving awareness and emotion attributes as endogenous variables. As a result, driving satisfaction of roundabout operation is directly influenced by delay reduction, safety improvement, capacity increase, sight improvement, severity accident reduction, and bicycle convenience and indirectly gender, age, driving time, and driving experience. Law obeyance, driving concession, traffic sign obeyance, and interposition do not statistically shows significant on satisfaction. As a result of Analytical Hierarchy Process (AHP), the turning radius of geometry and the driving behavior are important elements for roundabout safety.
